T 0 all whom it may concern 'Be it known that l", SAMUEL Lilzlnloli, of Edgewater Park, in the State of New Jersey, have invented a certain new and useful Improvement ill l'lolders :t'ol- Printing-Surfaces, .whereof the 'following is a specification. reference heilig had to the aeeonlpanyingI drawings.

This application is a division ot application Serial #584-202. tiled 4September '28, 15H0. for LetterA lateut of the llnited States tol' improvement ill duplicatillggg-lnaellines.y

My invention relates to a printing lna.

chille havingr a l'elllo\'ahle printing.;r form, and the ohject oi the invention is to provide simple and ell'ective means for readily locking the form in a machine alld unlocking it therefrom.

My invention is particularly well adapted for emhodinlent in a rotary office printingn machine and may he employed to hold a ilcxihle type chan@ ill such machine. Such an embodiment may he conveniently used for producing matter having' the appearance ot' typewriting. alld` in that case, it is desirahle to provide the ink hy nleanh` o l a tahric extending across the type torni. the tabric. being suitably inked, aa desired.

My invention includes the' various novel features of construction and arrangement hereinafter nlol'e definitely specified.

convenient emhodilnent ot my invention is shown in the drawings` hereot and conlpraes a rotary drinn. nieanf.; thereon for holding;r allout the drum. in Aa` segmental coursiaa tlexihle type chaee carlyillgT rows of `individual type. and a rotary platen adapted to coact with Snell type when the drunl is rotated. Locking means for the type chase are shown, which are adapted to he actuated hy a ypartial rotation of the drum, when deeiled` as hereinafter more fully explained.

.In the drawingsz-Fignre I is a fragmentary elevation ot the right; hand side ot a duplicating machine en'lloodyingr my invention. Fig. ll is a vertical sectional 'View of the drum of Said machine. Fig. lll: is a fragmentary pla n. view or the 'delcihloehase shown in section in Fig. H. Fig. is a l'aglnentary plan View ot theinlring sheet,

shown in' section inFig. lll.

lin eaidpgures, the duplicating' maehine' fran'le 1 supports the rotary printing drum S, having,l lts shat't 9 with the operating handle 1L); at one endjourllaled ill bearings ln said frame 1. Said drum 8 carries type set in a detachable flexible chase, :which as .shown in Figs. II and IH comprises the channel barev 26 which are maintained in parallel relation by the flexible handsf connected with the opposite end attaehi plates-28 and 29 extending transversely witg respect to said bands: said bars and 'plates being conveniently riveted to Said bands 27 as indicated in Fig. HI. Said plates 28 and Qt) have holes 30 and 3l, to engage attachinglneans on said drum` including the pair of stationary hook studs B2 and the l air ot oscillatory hook levers 3l projecting rom theleirclnnterence of said drunl as shown in Figa ll and respectively adapted to engage in Said holesl 30 and 31. Said hook levers ill are carried b v the rock shaft 35, which as indicated ill Figs. li and II is journaled in the opposite ends of said drum 8 and has the aprilier BT encirelingsaid Shaft Jlh'engaging tho pill 8S on 4Said Shaft, and the pill 8S) on said druln and tending to'rock said shht't :l5 to presa aid hook levers 34 ill the direction of the arrow adjoining Said sharl't :l5 in Fin'. ll. and thas wra said cla e tightly around the drum. Sai 'shaft fnllaa an arm l1 with a pin 42 exterior to aaid drinn tl. h v which said shaft may be turned when said pin ia engaged by the catch lever 43. Said lever is pivoted at in `the frame. and has the springr litrtendirl I' yto hold it aside from the path in which sai crank pln l2 is carried hy the rotation of the drum S in said frame.` 0n the outer side of the fralneplate l. is a linger knoll rotation of the drinn by its crank 12 causes' the pin 42 to catch in the notch ini-the end oli-the" Catch lever and he stopped thereby, soqthat n slight farther rotative movement offthe drum swings the. hook levers 34 to. the

opposite end otther range of movement.

This enables a ohaseto be installedon the drum or unlocked therefrom, as the case 111.4521."`v`

placed the posimty be. The knob 4Z.

tion shown in Fig. I so that it may be conveniently depressed by the thumb of a hand 'grasping the crank l2, thus leaving` the operators other hand free to hold the chase.

Any'desirable means may be employed for inking the type in the chase. For example, the drum may be provided with means to detachably hold stretched over the' type 25 in' stationary relation therewith the ink transfer sheet of textile fabric shown in Figs. II and IV having the attaching plates 51 and 52 With pairs of holes 53 and 5ft at its respectively opposite ends; the pair of stationary studs 55 on said drum being adapted to engage in either pair 'of said holes 53 of the plate 51, and, the plate being engaged by the pair of leashes projectingfrom said drum, including the hooks 56 engaging in' the holes 54 and connected by the exible metal tapes 59 to the spiral springs 60 carried in the tubes 6l Which are in rigid relation With said drum 8. Said plate 5l is provided With two pairs of holes 53 so that said sheet may be held in diii'erent positions to permit it to be uniformly worn out. Either said ink transfer sheet 50 or .the type 25 may be reinked after each printing impression, said sheet 50 being employed to produce impressions resemb ing typexvriting.

The detachable chase above described is the subject matter of my Letters Patent of the United States' 989,277 dated April l1, 1911.

I do not desire to limit myselt1 to the precise details of construction and arrangement above described as it is obvious that various modifications'may be made therein Without. departing from the essential features of my invention as dened in the appended claims.

I claim l. The combination with a frame; of a printing couple including a rotary drum journaled in said frame; means on said drum arranged to engage a 'fiexible chase,

including a pair of stationary hooks and a pair of oscillatory hoo-ks projectingr circumference of said drum; a siaft jourlnaled in said drum and carrying said oscillatory hooks; a spring tending to rock said shaft and press said'hooks in one direction; a crank on said hook shaft exterior'to said drum; a catch lever pivoted in said frame;

' a spring arranged to normally present said lever aside from the path of said crank; and, a handle on said catch lever extending exterior' to said frame, whereby said lever may be manually set in the path of said crank to rock .the latter and press said hooks in the opposite direction.

2. The combination With a frame; of a printing couple including a rotary drumV .Journaled in said frame; means on said drum arranged to engage a flexible chase,

from the' including a pair of stationary hooks and i. pair of oscillatory' hooks projecting from the circumference or". s'aid drum; a shaft jonrnaled in said drinn and carrying said oscillatory hooks; a springtending to rock said shaft and press said hooks in one direction; a crank on said hook shaft exterior to said drum, and a movable stop adapted to he positioned to engage the crank when the drum is rotated.

3. A printing drum having means arranged to engage a chase7 including a pair ot' stationary hooks and a pair of oscillatory hooks projecting from the surface ot said drum; means including a crank exterior to said drum whereby said oscillatory hooks may be moved, and a movable stop adapted to be positioned to engage the crank when the drum is rotated.

4. A printing drum having means arranged .to engage a chase, including a pair of stationary hooks and a pair of movable hooks projecting from the circumference of said drum, said movable hooks extending Within said drum: spring means Within said drum whereby said movable hooks may applv tension to 'the chase, and mechanism for automatically releasing said movable hooks consequent npon a partial rotation ot the drum.
